Throughout speed about CC26XX

simon chen

Hi,

Currently, I am working on CC26XX, and I have some question to ask:

1. What's the max throughout speed between CC26XX and CC26XX, and what's max speed between cc26xx and mobile phone? Do you have any testing on that, If have, could you share them for me?

As we know, BLE transmit interval between 7.5ms~4s, and for every transmit, 20bytes is max. That means the theory max speed is 20bytes/7.5ms=2.67kbytes/s, is that right? In my pre-product, I use nrf51822, it can transmit 6 packs between one intreval, that means 20bytes*6/7.5ms=16kbytes/s.

2. Could cc26xx support private protocal stack? And if use private protocal stack, what max speed can be reach, and what can I do to start? Is there any private protocal stack demo to be share?

thanks.

Simon,

Using BLE maximum throughput typically depends on how many packets per connection interval the Central (phone) side will listen to before closing the connection event.
The CC26XX will also allow you to send more than one packet per connection interval but iOS will typically not receive more than 6 packets per interval even if the theoretical maximum is higher. TI currently provides protocol stacks for Bluetooth LE and Zigbee.

Regards,
Svend

Hi Svend,

Do you have any speed test result berween cc26xx evk ?

and, If I want to start simple private protocol stack, Is there any API or material?
